PASTING QR GLUINGMACHINE.

SPECIFICATION forming part of Letters Patent No. 741,597, dated October 13, 1903. Application filed iluly 10,l903. Serial No. 164,982. (No model.)

To aZZ whom it mag concern.-

Be it known that I, FREDERIOKD. TAYLOR, a citizen of the United States,'residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Pasting or Gluing Machines, of which the following is a specification.

This invention relates to a machine for api0 plying paste, glue, mucilage, or similar adhesive compounds to sheets or websof paper, cloth, and the like fabrics.

The object of the invention is to provide a simple compact machine which will apply the desired quantity of adhesive substance to the surface of the sheet in a rapid and satisfactory manner.

This machine is so constructed that the sheet is fed between rolls at the top nearthe front and immediately coated with adhesive compound and delivered to an apron, which carries it down in front'of and under the machine to another section of the same apron, whichcarries it beneath the machine to the z 5 rear with the adhesive side up.

Figure 1 of the accompanying drawings shows a side elevation of a machine that embodieslthe invention. Fig. 2 shows a vertical transverse section of the machine. Fig.

0 3 shows a vertical longitudinal section of the machine, taken on the plane indicated by the broken line 3 3 of Fig. 1, looking in the direction pointed by the arrows. Fig. 4 shows a view of the back of the adhesive-receptacle,

and Fig. 5 shows aview of one of the rolls and a finger-bar.

The side frames 1 of this machine are formed toany suitable design and are connected by any suitable means. The recep- 0 tacle 2, which is to contain the paste, glue, mucilage, or other adhesive compound, has flanges 3 projecting outwardly from the lower edges of its ends. These flanges fit and are adapted to move in grooves between ribs 4,

cast on the inside of each side frame. The adhesive-receptacle is adjusted toward the front and back by means of screws 5, that turn in the ends of the supporting-flanges. Each of these screws extends through a slot in a plate 6, that is secured to the back edge of the side frame by a screw 7, which also passes through a slot in the plate, so that when the holding-screw is loosened the plate may be drawn side'wise to permit the complete removal of the adhesive-receptacle. On the'left side of Fig. 4 the plate is shown as holding one of the adjusting-screws of the adhesive-receptacle, while on the right side of that figure the plate is drawn out to show the mannerin which the end of the groove is freed, so that the receptacle can be removed from the side frames. Lugs 8 are cast on the inside of the bottom of the receptacle, and secured to these lugs is a plate 9 with a scrapingedgelO. By turning the adjusting-screws the adhesive-receptacle may be moved toward the front or back for adjusting the position of the scraper that is within.

Below the adhesive-receptacle is a watertank 11, which has flanges 12 projecting out- 70. wardly from the lower edges of its ends. These flanges fit and are adapted to move in grooves between ribs 13, cast on the inside of the side frames. Handles 14 are preferably secured into the rear ends of the flanges to facilitate the removal of the water-tank.

Extending from one side of the frame to the other below the watertank are' pipes 15. These pipes are adapted to be connected with a gas -supply, and. they have perforations I through'the upper sides, so that they may be used as burners for heating water in the tank.

If desired, a common electric heater may be used for heating the water. If the machine is to be used for applying paste or mucilage, the water tank and heater need not be used; but if the machine is to be used for applying glue or the like adhesive water is put into the water-tank and heated by lighting the gas supplied" through the go burner-pipes or by an electric heater, whichever is the most convenient.-

A tube 16 isarranged to open through the bottom of the adhesive-receptacle, so that water may be'supplied to the water-tank without interfering with the operation of the machine. An opening 17 is also made through the bottom of the adhesive-receptacle and provided with a plug 18, whereby the adhesive may be allowed to run out and the recep- 10o tacle cleaned without removal from the machine.

Extending across the machine and carried by a shaft supported by hearings on the upper-edges of the side frames, so as to dip into the adhesive receptacle, is an adhesive-applying roll 19. Extending transversely back of the applying-roll and supported by a shaft held by blocks 20, that are adjustable on the upper edges of the side frames, is an adhesive gage-roll 21. This roll determines the amount of adhesive compound that is carried up on the surface of the adhesive-applying roll. The blocks which support this shaft are thrust rearwardly by springs 22 and are adjusted forwardly by screws 23. By turning the screws the gage-roll may be brought closer to or farther from the adhesive-applying roll.

Extending transversely in front of the applying-roll on a shaft held by bearing-blocks 24, adjustable in the side frames, is a feedroll 25. This roll is forced from and adjusted toward the adhesive-applying roll in the same manner as is the gage-roll.

A roll 26 is arranged to extend across the machine above the feedroll. 7 This roll is preferably supported upon conical points 27, which are not screwed in tightly, so that the roller will rest loosely upon the top of the feed-roll. This roll holds the sheet as it is passed into the machine down upon the feedroll.

From a bar 28, that is secured to the tops of the side frames, fingers 29 project downwardly back of the holding-roll and feed-roll, so as to guide the sheet which is to be coated down between the feed-roll and the adhesive-applying roll. Fingers 30, secured to the adhesivereceptacle, project upwardly and bear lightly against the surface of the adhesive-applying roll below the feed-roll, so as to insure the loosening of the sheet that has been coated with the adhesive substance from the adhesive-applying roll.

A loose pulley 31 and a driving-pulley 32 are mounted upon a stud projecting from one side frame. Connected with the driving-pulley is a gear 33, that meshes with a gear 34 on the end of the applying-roll shaft. Meshing with the latter gear is a gear 35 on the end of the feed-roll shaft and a gear 36 on the end of the gage-roll shaft.

Extending transversely of the machine below and a little in front of the feed-roll and supported by bearings in the side frame is the upper apron-roll 37. Extending transversely considerably lower and somewhat to the rear is the apron-roll 38, and extending slightly below and a little in front of this roll is a guide-roll 39. Below the guide-roll is the lower apron-roll 40, and supported by suitable bearings on the table considerably in the rear of the machine is the shaft of the rear apron-roll 41. The endless apron 42 passes around these rolls, as is shown in Fig. 2, so as to form a downwardly and rearwardly inclined section 43 directly beneath the adhesive-applying and feed rolls, and a horizontal section 44, that passes from below the inclined section beneath the machine to the rear.

On one end of the shaft of the feed-roll is a gear 45, that meshes with a gear 46, which is in mesh with a gear 47 on one end of the upper apron-roll shaft.

The operator first adjusts the adhesive-receptacle, so that the scraper in its bottom will properly clean the adhesive compound from the surface of the adhesive-applying roll, and then adjusts the gage-roll, so that the exact desired quantity of adhesive compound will be carried around on the surface of the applying-roll. The sheets are then fed by hand or the end of a web started into the machine between the feed-roll and the holding-roll. These sheets are guided down between the feed-roll and the applying-roll "by the upper fingers, and after having one surface coated with adhesive compound they are loosened from the surface of the applying-roll by the lower fingers and allowed to drop upon the inclined section of the traveling apron, which is so moving that it carries the sheets downwardly and deposits them upon the horizontally-moving section of the apron, which carries the sheets beneath the machine to the desired locality at the rear.

This machine is very compact, simple to construct, and easy to operate. The sheet or web of paper, cloth, or other material is coated immediately after it is started in the machine with glue, paste, mucilage, or other adhesive compound and at once carried down by simple means and passed out beneath the machine in the vicinity of the heater, which tends to hasten the evaporation of superfluous moisture from the adhesive compound, so that it will readily adhere when the sheet is applied to the article to be covered. The parts are capable of easy adjustment, so that the exact amount of adhesive compound can be applied to the surface to be coated, and the sheet is carried down and out so quickly that it does not have a chance to warp and curl before it is delivered in position to be used.

I claim as my invention- 1.
